Future Protein Sources in Sports Nutrition: Sustainable Solutions

PURPOSE OF REVIEW: This review evaluates the potential of alternative protein sources, including plant-based proteins, insect proteins, mycoproteins, microalgae, and cultured meat, in meeting the increasing demand for sustainable and functional protein solutions in sports nutrition. RECENT FINDINGS: Studies indicate that alternative protein sources provide significant environmental benefits, such as reduced greenhouse gas emissions and lower water use, while delivering essential nutrients to support athletic performance and recovery. Advances in technology and production methods have further enhanced their feasibility as replacements for conventional animal-based proteins. Integrating alternative protein sources into sports nutrition offers a dual benefit: meeting athletes' dietary requirements and supporting global sustainability goals. These protein sources pave the way for innovative, environmentally conscious dietary practices in sports nutrition, marking a pivotal shift toward a more sustainable future.
